Constellation analysis of holographic projection materials

Description and application of holographic projection

Front projection holographic display is a 3D technology, which originally refers to the technology of recording and reproducing real 3D images of objects by using the principles of interference and diffraction. Then, under the guidance of science fiction and commercial propaganda, the concept of holographic projection gradually extended to commercial activities such as stage performances and exhibitions. However, the holographic technology that we usually know is not holographic projection in the strict sense, but a holographic projection technology that uses pepper illusion and edge blanking to achieve 3D effect.

"Holography" comes from the Greek word "Holo", which means "complete information", that is, it contains amplitude and phase information in light waves. Ordinary photography can only record the intensity information (amplitude) of light, and the depth information (phase) will be lost. In the interference process of holographic technology, the superposition of peaks will be higher, and the superposition of peaks and valleys will be flattened, resulting in a series of irregular stripes alternating between light and dark, thus converting phase information into intensity information and recording it on photosensitive materials.

applied range

The application of holographic projection technology on the stage can not only create a three-dimensional illusion in the air, but also make the illusion interact with the performers to complete the performance together and produce shocking performance effects.

Judging from the application of holographic projection technology in the runway show released by Disel fashion, the beautiful holographic projection picture takes the audience to another world with the walking of the model, as if letting the audience experience the dual world of virtual and reality. Then, with the application of holographic projection technology in Norman, the master animator of Dream Theater, the stage art and the stage position have appeared extraordinary fusion in the same space, showing the audience the latest innovation achievements of the world multimedia art. The service and sales industries need the mass base most, and attracting consumers to the maximum extent is the king. The application of holographic projection technology in this respect has gathered people's eyes from a new angle and aroused consumers' desire for consumption.

The ultimate goal of convention and exhibition industry is how to sell products, and how to attract the attention of exhibitors to the greatest extent has become the magic weapon of this industry. Aiming at the exhibition industry, a 360-degree virtual imaging system is launched in real time, and three-dimensional images are suspended in mid-air for imaging, creating an illusory and real atmosphere with unique effects and full sense of science and technology. It has opened up a new marketing direction for the convention and exhibition industry.

Holographic projection system is a system that records and reproduces the real three-dimensional image of an object by using the principles of interference and diffraction. Three-dimensional animation is a brand-new thing, which has changed people's aesthetic attitude towards the traditional stage sound and photoelectric technology. Scope of application: product display, automobile and clothing conference, stage program, interaction, bar entertainment, interactive projection of places, etc.

Holographic scene means that the audience can see the phantom in the mouth of the generator, that is, a circle. The holographic projection system suspends the three-dimensional picture in the air of the real scene for imaging, creating an atmosphere in which reality and reality coexist. The effect is peculiar, the depth is strong, and it is difficult to distinguish between true and false. Fashion and beauty, with a sense of science and technology; Transparent roof, real space imaging; Bright colors, high contrast and high definition; Have a sense of space and perspective, forming an illusion in the air; The middle can be combined with things to realize the combination of images and things; Can also be equipped with a touch screen to achieve interaction with the audience; Can be made into four windows as needed.
